ROLL FOR IRONING MACHINES.

Application filed September 28, 1921. Serial No. 503,937.

To all whom t may concern:

lle it known that I, CHARLES E. a citizen of the United States, Kew Garden, Richmond Hill. in of Queens, State of New ed certain new and useful Improvements in Rolls for Ironing Machines, of which the following is a full, clear, concise, and exact description.

This invention relates to ironing machines or inangles, and particularly to the construction of rolls or cylinders employed therein.

It is an object of the invention to provide an ironing roll which is simple in construction, combining strength and rigidity With a minimum of weight, and in which the cost of manufacture is reduced to a minimum.

It is a further object of the invention to provide a novel and improved means for locking a fabric cover upon the ironing roll.

Other objects and features of the invention will appear from a consideration of the following description taken in conjunction with the accompanying drawing and the appended claims.

In the drawing, Fig. 1 is a View in perspective showing the preferred method of shaping the ironing roll; Fig. 2 is a perspective View of the completed cylinder; Fig. 3 is a perspective view of the assembled roll structure comprising a main ironing roll and a short auxiliary roll, showing the supporting spiders and the fabric cover secured in place; and Fig. 4 is an enlarged end elevation of the ironing roll.

Referring to the drawing, in its preferred form, the invention contemplates forming the sheet metal cylinder 1 to shape around a cylindrical mandrel, such as that shown at 2. The mandrel 2 has a diameter less than the diameter of the supporting spiders upon which the cylindrical roll 1s subsequently mounted so that, in assembling, the longitudinal edges of the cylinder are somewhat separated to form a slot. The coinpleted ironing roll is rigidly secured to a shaft 3 which passes through the hubs 4 of end and intermediate spiders 5. The hubs are preferably keyed to the shaft 3 in any suitable manner, as by means of screws 6. Both end and intermediate spiders 5, which may be of cast iron, for example, are formed with comparatively wide peripheral flanges 7, as best shown in Fig. 3. These anges Rennie, residing at the county York, have inventare here shown lying wholly on one side of 'of the cylinder has purposely been made smaller than that of the spiders, this slot being so positioned as to register with slots 9 formed in the flanges of the end and intermrdia-tc spiders. The slot 8 is of smaller width than the slots 9, as shown in Fig. 3 and therefore serves to tightly clamp one edge of a strip of fabric or felt l0, which is wound around the cylinder. It will be seen that the clamping effect of the spread cylinder serves not only to clamp the padding in place, but also to prevent the slipping of the roll upon the spiders. While in ordinary practice it is preferable to x the cylinder' to the spiders by means of screws l1, or in any other standard manner, it will be obvious that the grip obtained by the clamping effect of the spring cylinder upon the supporting spiders in accordance with the invention is sufficient to hold the cylinder firmly, and at the same time permits the ready dismembernient of the parts. The clamped edge of the pad 1.0 forms a wad within the recesses 9 in the flanges of the spiders 5 which further serves to prevent the rotation of the sheet cylinder with respect to its supporting spiders. The method of manufacturing herein described avoids the necessity of securing a fit between the spiders and the cylinder to cause the longitudinal edges of the cylinder to abut, and at the same time, provides means for locking one end of the fabric wrapping.

The auxiliary roll provided at the left of the main ironing roll, as shown in Fig. 3, embodies the same structural principles as described in connection with the main roll. In this case a single spider is employed and is so positioned as to give a maximum support to the cylinder. The small auxiliary roll is keyed to the main shaft in the same manner as the main roll, so that in the assembled machine, motion imparted to the main roll by the driving mechanism is communicated to the smaller roll. The roll shaft is usually mounted in fixed bearin s in 'the supporting frame of the mangle, t e smaller roll extending outside the frame to permit its use without interfering with the operation of the main roll.

Since certain changes obviously may be made in the construction of the ironing roll herein shown and described and still remain Within the scope and spirit of the present invention, it is to be understood that the invention is not limited to any specific structure except as defined by the scope of the appended claims.

What is claimed is:

1. A roll for ironing machines comprising a support having a recess therein, a sheet metal cylinder mounted thereon With the adjacent longitudinal edges of the cylinder separated to form a slot registering with said recess, and a fabric cover wound around said cylinder, one end of said fabric disposed Within said slot and ,recess and held therein by the clamping action of the abutting ends of the cylinder.

2. A roll for ironing machines which coinpriscs an annular spider, a slotted sheet metal cylinder mounted upon said spider, said spider having a recess in its peripheral edge 1n registration with the slot in said cylinder` and a fabric cover wound around said cylinder, one end of said fabric disposed Within the slot in the cylinder, and the recess in said spider and grlpped by the adjacent edges of said cylinder.

3. `An ironing roll for ironing machines, comprising an annular spider having a recess in its peripheral edge, a sheet metal cylinder secured to said spider and having a slot in registration with the recess in said spider, said slot having a Width less than the width of said recess, and a fabric cover wound around said cylinder, one end of said fabric disposed Within the slot in the cylinder and the recess in said spider and gripped by the adjacent edges of said cylinder.

In witness whereof, I hereunto subscribe my name this 26th day of September A. D., 1921.

CHARLES E. REDDIG.
